At CeBIT, Plextor showed off a yet unnamed line of consumer SSDs featuring 19 nm triple-level cell (TLC) NAND flash memory. The series consists of 128 GB, 256 GB, and 512 GB variants, with 256 MB, 512 MB, and 768 MB of DDR3 DRAM cache, respectively. The three are driven by Marvell 88SS9189 processor, and are built in the 2.5-inch form-factor, with SATA 6 Gb/s interface.

The 128 GB variant offers sequential read speeds as high as 530 MB/s, with up to 380 MB/s writes, and 72,000 IOPS 4K random write performance. The 256 GB variant ups that with 540 MB/s reads, and 450 MB/s writes. Leading the pack is the 512 GB variant, with 540 MB/s reads, and 465 MB/s writes. The lineup is expected to be launched this August.

In reality most people would be totally unable to tell the difference in SSD speeds from the slowest to the fastest models, other than in benches, which don't necessarily represent real world perrormance.

These SSDs are meant to be mainstream, i.e. lower cost SSDs, not benchmark specials. What's of more significance is their compatibility and reliability, a common issue with most SSDs even after years of development. Plexto has a better track record than others in that respect.
